The ultimate revenge drama, starring the most popular Korean male actor in the world, is a bit flawed in the beginnning few episodes but anyway, the rest are powerful episodes which boasts one of the most dramatic K-drama I've ever seen. I say the drama is "flawed" only because, after creating unbelievable dramatic tension in the first episode with a shocking - and very hard to watch - mass assassination scene, the drama then focuses more during the next four to five episodes on the lead male character's attraction to a girl who is a bodyguard at the "Blue House" (the Korean equivalent of the U.S. White House). I think that was a mistake: if you are going to write a revenge drama then revenge should be the main focus of ALL the episodes. A romance is fine but it should be woven into the story lightly as a true backdrop to what's really going on in this story: two men's thirst for revenge against the people who ordered the mass assassinations of their fellow citizens. To be fair, after about the fifth episode, the drama gets back on track on the revenge theme, and by the end that theme delivers in spades. Any lag in the story at the beginning was the writers' fault, not the actors' fault - they all delivered fine, unforgettable performances, especially the actor who plays Lee Min Ho's adoptive "father" in the story, actor Kim Sang-joong. He blew me away with his intensity, perhaps because in real life he has been a Marine and a cop, as well as an actor. At least his character never loses focus on his ultimate goal of revenge, which is far more believable than Lee Min Ho's character's obsession with a girl. There’s something about Kim Na Na’s solemn and innocent face that keeps Yoon Seong want to ward off any trouble and stand protective. As time passes he gets drawn to her but his goals prevent him from being open with her. Stolen glances, silent exchanges are all they can afford for the time being. I really like Kim Na Na’s character. Its well drawn out and Park Min Young plays it perfectly, right down to that sweet smile which hides all her worries and troubles.I really liked her acting When his adoptive father finally has had it with Yoon-sung's interference in his plans to execute the Council of Five, they possibly try to kill each other at the same time. It is not a pretty sight, in fact it's one of the most compelling and mesmerizing scenes in K-drama history. One of the things that make this drama worthwhile are the tension filled fight scenes. Well set and choreographed, the battle sequences are charged and exciting, perfectly displaying our feature character. Prosecutor Kim Yeong Ju who plays a vital role in this revenge. As a prosecutor he strives hard to catch the corrupted politicians before City Hunter (an alias given by the public to Lee Yoon Seong). But unfortunately he falls short and is always a step behind the mastermind, Yoon Seong. His will and determination to serve Korea justly is commendable. Another character is Jin Sae Hee, who is a vet and Kim Yeong Ju’s ex-wife. She is played by Hwang Sun Hee, another beauty. She is like an elder sister to Kim Na Na and is very helpful. Throughout the season she shares a cordial relation with Kim Yeong Ju despite their divorce. It gives you hope again and I kept on wishing that they would mend their broken relation. 1 thing I so so so so badly wanted to see/ wished was that they would focus more on Kim Yeong Ju and Jin Sae Hee. Though they were part of the main cast, I feel they didn’t receive as much attention as they should have. Anyway, all in all, its a very enticing, revenge-scheming, thriller with a dash of romance.
